[0080]
Hereinafter, the usage method of a present Example is explained in full detail. The underground pipe 1 to be repaired is exemplified by a well, and the repair site A is exemplified by a corrosion hole.
[0081]
In a state where the annular repair member 2 is not locked to the locking portion 22 of the transport body 4 (when the annular repair member 2 is not attached), it is connected to the wire 30 from the upper opening of the underground buried pipe 1. The carrier 4 is moved down. During this descent movement, the lower illuminator 14 and the lower camera 15 are used to investigate whether or not there is a repair site A that requires repair in the underground pipe 1. If the repair site A does not exist, the transport body 4 is returned to the ground to complete the investigation.
[0082]
When a repair site A that requires repair is discovered, the carrier 4 is moved up and down so that the repair site A is in the viewing direction of the camera 7 (main camera), and the lower body 4b is moved in the circumferential direction by the rotational drive source 6 Rotate to.
[0083]
Subsequently, the operation mechanism 5 is operated, and the spray material is sprayed onto the repair site A using the spray mechanism.
[0084]
When the spray material is sprayed, the fixing mechanism 10 is operated as necessary, the pressing body 11 is protruded, the abutting portion 24 is abutted against the inner surface of the underground buried pipe 1, and the vertical position of the transport body 4 is set. It may be fixed.
[0085]
Subsequently, the transport body 4 is once pulled up, and the annular repair member 2 is locked to the locking portion 22 of the transport body 4. Further, the preliminary annular repair member 2 ′ is held on the holding portion 8 of the transport body 4.
[0086]
Subsequently, the carrier 4 connected to the wire 30 is moved down from the upper opening of the underground pipe 1 again, and the lower illuminator 14, the lower camera 15, the camera 7 (main camera), etc. The transport body 4 is operated so that the viewing direction of the camera 7 is the repaired part A sprayed with the spray material.
[0087]
If the connecting body 3 is cut as it is, the repaired part A will be located between the left and right end parts 2a, 2b of the expanded annular repair member 2, and the repaired part A will be poorly repaired. By operating the drive source 6 and rotating the lower body 4 b, that is, the annular repair member 2 in the circumferential direction, the repair site A is positioned other than between the left and right end portions 2 a and 2 b of the annular repair member 2. The rotation of the lower body 4b in the circumferential direction is best at 180 °.
[0088]
Subsequently, the rotation drive source 6 is stopped, and the operation mechanism 5 is operated to such an extent that the tapered portion 49 does not push the pushing portion 47 to cut the connecting body 3, thereby reducing the diameter of the ring. The diameter of the repair member 2 is expanded, and the annular repair member 2 is attached to the inner surface of the underground buried pipe 1 via the spray material by the increased diameter, and the repair site A is blocked by the annular repair member 2 by the attachment. To do.
[0089]
At this time, the camera 7 exists at the height of the repair site A and the annular repair member 2, and the camera 7 visually recognizes the repair site A from between the left and right end portions 2a, 2b of the annular repair member 2. The height of the annular repair member 2 does not change due to the rotation in the circumferential direction, and the repaired portion A can be reliably repaired by the rotated annular repair member 2.
[0090]
Further, the annular repair member 2 that has been expanded and attached to the inner surface of the underground buried pipe 1 has been removed from the locking portion 22 of the transport body 4, so that the spare mounted on the annular repair member 2 has been removed. The annular repair member 2 ′ moves downward and is locked to the locking portion 22.
[0091]
Subsequently, the rotational drive source 6 is operated, and the camera 7 is used to check whether or not the repaired part A has been reliably repaired by the annular repair member 2.
[0092]
If the repair has been performed reliably, the fixing mechanism 10 releases the fixing of the upper and lower positions of the transport body 4 and recovers the transport body 4 from the upper opening of the well.
[0093]
In addition, since the spare annular repair member 2 ′ remains in the transport body 4, if the repair in the repair work is poor, or the vertical width of the repair site A is the upper and lower of the annular repair member 2. For example, when the repair is not possible with the integral annular repair member 2 that is wider than the width, for example, the fixing of the transport body 4 by the fixing mechanism 10 is once released and the vertical position of the transport body 4 can be changed by the moving mechanism 9. Then, the repair site A is repaired again by the spare annular repair member 2 ′ in the same procedure as described above.
[0094]
According to the above procedure, the underground pipe 1 can be repaired using this embodiment.
[0095]
Further, when the spray material is solidified due to the change over time, the spray material firmly connects the annular repair member 2 and the underground buried pipe 1.
[0096]
The operation of each part is performed by remote operation using a remote controller or the like. The images from the camera 7 and the lower camera 15 are copied to a monitor installed on the ground, and the remote operation is performed while viewing the monitor.

[0105]
In addition, since the spare annular repair member 2 ′ is provided, it is not necessary to repeatedly remove the transport body 4 from the inside of the underground pipe 1 every time there is a repair failure or the number of repair sites A. The repair site A can be repaired.
[0106]
Further, the diameter of the annular repair member 2 can be increased in a state where the transport body 4 is fixed by the fixing mechanism 10, and also in this respect, the repair site A can be reliably concealed by the annular repair member 2.
[0107]
Also, since the spraying material reservoir part 42 for storing the spraying material and the compressed air reservoir part 41 for storing the compressed air for blowing out the spraying material are provided as separate containers, the structure of the spraying mechanism should be made compact. Therefore, the carrier 4 can be made compact, and the thin underground pipe 1 can be repaired.
[0108]
Further, since the repair site A can be repaired only by spraying the spray material, for example, when the necessary repair level is small, the amount of the repair member used is minimized by only spraying the spray material. As a result, it is possible to facilitate the repair of a large number of repair sites A.
[0109]
In addition, this Example can implement repair not only with a vertical shaft type such as a well but also with a horizontal shaft type such as a sewer pipe. In this case, the configuration of the apparatus is the horizontal direction of this embodiment.
[0110]
Further, as the structure of the spraying operation part 44, the taper part 49 does not only push the pushing part 47 of the compressed air reservoir 41 by the back-and-forth movement of the spraying action part 44, for example, the spraying action part The projection is pushed by the pushing portion 47 by moving back and forth 44, and the pushing is released after the projection passes over the pushing portion 47. Further, after the release, the operation mechanism 5 If the cutting part 19 is configured to cut the connecting body 3 of the annular repair member 2, after the spraying material is sprayed, the repair by the annular repair member 2 can be performed continuously, and the repair workability is improved accordingly. It will be a thing.
